This is a sample of Ouroboros and other glass pieces. I do not know the specifics of each individual glass piece. Please use them for crafting small items. Shipping is set for 4-6 days, but we ship as soon as preparation is complete. Shipping will be via Click Post. We will pack carefully, but there is a possibility of breakage during transit. Especially when purchasing multiple items, they will be packed together, making them more prone to breakage. We do not offer compensation for breakage. If you would like fragile handling, we can change to express delivery with added shipping costs. Please contact us before purchasing. Please note that we use recycled materials such as newspapers and cardboard for packaging. We will pack your order upon payment completion, so we cannot accept requests for combined shipping or changes after that. The limit for combined shipping is 3 pieces (or 4 pieces if they are small) per package. We will offer a discount on the second item and onwards per package.
